Itaewon Class was a breath of fresh air in that it takes familiar themes that we know well such as revenge and childhood affection and develops them in unique and unexpected ways. The cast is colorful and interesting and the leads are well acted and unlike your typical drama heroes. It doesn't lose steam until the end and there's plenty of jokes and exciting moments to go around. The OST only adds to the whole experience. The first few episodes are very much a setup and I didn't feel like it'll keep me interested but I realized I was slowly getting attached to the characters and it eventually became one of my favorite dramas ever.
